Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
The MSVDX driver in Apple iOS before 8.4.1 allows remote attackers to cause a denial of service (device crash) via a crafted video.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

A denial of service vulnerability exists in the MSVDX video decoder driver in Apple iOS versions prior to 8.4.1. Remote attackers can cause a device crash by tricking users into playing a specially crafted video file. The vulnerability has a CVSS score of 7.1 (HIGH).

MitigationUpgrade affected iOS devices to version 8.4.1 or later, which contains the fix for the MSVDX driver vulnerability.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Check the iOS version installed on the device
    On the device, go to Settings > General > About > Version. Alternatively, connect the device to a computer with iTunes or Finder and view the device information.
    Affected if The reported iOS version is 8.4 or earlier (for example, 8.4, 8.3, 8.2, 8.1, 8.0, 7.x, or earlier)
  2. Confirm the device is an iPhone
    This vulnerability affects iPhone OS (iOS). Verify the device type through Settings > General > About > Model Name, or check the physical device.
    Affected if The device is an iPhone running a vulnerable iOS version
  3. Identify if the MSVDX video decoder is accessible
    This is an internal kernel driver (MSVDX) used for video decoding. There is no user-accessible configuration to inspect. The vulnerability is triggered when the device processes a specially crafted video file.
    Affected if The device can play video files and is running a vulnerable iOS version

A user is affected if their iPhone is running iOS version 8.4 or earlier, since the MSVDX video decoder driver in those versions contains the denial of service vulnerability.
